Correlations between UV sensitivity, BCNU cytotoxicity and MGMT or ERCC2 expression in 14 human tumor cell lines

	Regression formula	r	p
UV-BCNU	y = 0.15x + 5.2^2-a	0.858	0.0001
UV-ERCC2 (protein level)	y = 28.7x + 9.7^2-a	0.874	0.0001
UV-MGMT (protein level)	y = −4.3x + 14.9^2-a	0.153	0.6017
UV-MGMT (activity)	y = −1.0x + 14.4^2-a	0.103	0.7255
BCNU-ERCC2 (protein level)	y = 148.7x + 36.5^2-b	0.786	0.0009
BCNU-MGMT (protein level)	y = 21.8x + 51.9^2-b	0.139	0.6348
BCNU-MGMT (activity)	y = 7.4x + 53.1^2-b	0.131	0.6515

↵2-a y represents UV sensitivity and x represents either BCNU cytotoxicity, ERCC2 protein level, MGMT protein level, or MGMT activity.
↵2-b y represents BCNU cytotoxicity andx represents either ERCC2 protein level, MGMT protein level, or MGMT activity.
